Trailer Notes

If you're going to use a trailer find out its max (GVWR) weight. Also how much it actually weighs, and its tong weight. What kind of hitch 2" ball, 2 5/16" Ball, Pintle hook or GI hitch, Goose neck, Fith wheel?, etc... Does it have electric breaks? are they 4 wire, 6 wire, or 7 wire? What is the GVWR, GAWR, GCWR of the pulling truck?
